Document what different states mean (e.g "eaten")

[dbr]

Describe the enhancement Being new to the OpenCue, there is a few references to "eating frames", and I couldn't work out exactly what that means (and thus things like the "Eats all dead frames for job" pacman button in the cuegui were mysterious)

Only as I write this I stumbled across the docstrings on https://github.com/AcademySoftwareFoundation/OpenCue/blob/d2057d3f1c3c01d5a78fedd9a22fe8400d91ec83/proto/job.proto#L409-L427 which explains it nicely, "Frame is eaten, acts like the frame has succeeded" - although a little more context would be helpful (like I the state exists to allow dependent jobs to continue, unlike leaving the frames as dead?)

Would be handy to have the states this documented in the glossary or similar
